You can import the NanoBrain Ant package in Unity directly with the Package Manager git package importer.

See Unity: Installing from a Git URL

Use the link from 'Clone with HTTP' (for example: https://git.passer.life/CreatureControl/Ant.git) In this way you can always retrieve the latest version by pressing the Update button in the Package Manager.

Optionally, you can use a tag to retrieve a specific version. For example: https://git.passer.life/CreatureControl/Ant.git#0.1.0. This will give you a stable version which does not change. Updating can be done by retrieving the package with a link to a new release.

Samples Installation

In the Unity Package manager, select the NanoBrain Ant package and look for the Samples tab in the details pane on the right. There you can import the Models.
